' 2 Claims. (CL 40--120) I I This invention relates 'to improvements in a memorantionto provide amemorandium calendar of the multileaved, flip-over type, in which a yearly period, for example, is divided into time-period subdivisions for easy rifiiing and reference, either in retrospect or in advance; a calendar in which a time period is subdivided into a plurality of day-sheetsthat are arranged so that for a given time period, a week for example, can be scanned in advance as to appointments and notations of other upcoming events; a calendar in which there is a plurality of sets of similar leaf-sets which are supported and mounted on their supports for flip-over manipulation and which when rested in one aspect or the other are maintained in proper alignment so that like spaces on the day sheets for a span of several days are properly aligned with respect to like time period subdivisions for each of the several days; and a calendar in which there is a plurality of similar leaf sets so constructed and arranged that one constitutes a terminal leaf or card of such nature that it and the associated day sheets can be easily segregated from the remainder for rifiiing retrospectively or forwardly with respect to any particular day or time period.

These and other advantages and objects of the invention will become more apparent during the course "of the following description of a preferred form of this invention which, when taken with reference to the accompanying drawings fully discloses and describes the invention.

In the drawings:

FIGURE 1 is a perspective view of the memorandum calendar;

FIGURE 2 is an end view of the calendar of FIGURE 1 with portions of the leaf sets broken away and shown in section in order to illustrate guide means employed vtherewith; and

FIGURE 3 is a perspective view of a guide strap which is employed in connection with this memorandum calendar.

The base of the memorandum calendar comprises a pair of angularly disposed supporting surfaces 10, 12 which form an upwardly open cradle having a valley 14 in its mid-portion. Valley 14 extends approximately normal to the user of the calendar. The cradle rests on a front supporting leg 16 and a rear leg 18 and will stand slightly inclined forwardly upon a desk or like surface due to greater heighth in leg 18 over front leg 16. The cradle being tilted or sloped toward the user is convenient for writing on the notation sheets or leaves of the leaf sets.

A pair of spaced apart arched guide bars 20, 22 rise above and are suported by the cradle in such a manner that they straddle the medially located valley 14. Prefenably guide bars 22 are of metallic rod material or the like. Their lower ends extend downward through holes 24 in supporting surfaces and 12, as can best be seen in FIGURE 2. Near their lower or free ends the guide bars 20 or 22 are provided with side notches 26. When their ends are inserted through the holes 24 and the legs are permitted to spring outward due to an inherent spring "2,990,638 Patented J 196 1 bias of the guide bars there is an interlocking between the notches 26 and the outer edges of the holes 24." This interlock holds the arched guides from accidental dislodgment. The arched bars can be removed of course by slightly compressing the lower ends of the legs together to dislodge the notches whereupon one can raise the guide member as a unit and remove it.

A plurality of similar leaf sets 28 constitute the memorandum pages of the calendar. Each leaf set may cutbrace a portion of a year or similar period of time, for example a month, two months, or a week, as may be de sired. Preferably I havedivided the note pages of a preferred form of the calendar into fifty-two leaf sets each covering a calendar week; This arrangement is shown in FIGURE 2 where there are sheets 30, 32, 34, 36 and 38 and terminal card40 comprising a leaf set for one week.

Each of the day sheets forming a leaf set is identically perforated and these perforations receive the legs of the inverted or arched guide bars 20 and 22, all as shown in FIGURES '1 and 2.

An inverted guide strap 42, preferably formed of relatively thin, springy metal in the manner shown in FIG- URE 3, has foot flanges 44, 46 standing in opposite directions from each other on each of the bottom edges of the guide strap. By means of notches 48 and 50 the guide strap 42 is secured in place between the lower ends of the legs of the guide bars 20, 22. The flanges 44, 46 rest on the supporting surfaces 10 and 12 respectively. The

spring action of the guide'strap when disposed beneath the guide bars provides broad upright faces in juxtaposition with the edges of the leaf sets on either side. Guide strap 42 holds the day sets and their components in appropriate alignment with each other. Thus the aligned ruled spaces for like time period subdivisions of the various days of a leaf set are properly correlated as is shown in FIGURE 1. For example, assume that the calendar is open and the user is interested in knowing what future commitments he may have at ten oclock in the morning of the following days. He need not flip any of the following days sheets because at a glance he can see all entries that are for ten oclock on sheets 34, 36, 38 or card 40.

Guide strap 42 because of the aligning and hold function at the edges of the sheets and cards permits the spacing of the two arches 20, 22 to be less than if strap 42 were omitted. This provides more clear unobstructed area for the user when making notes and eliminates interference with his hand as when writing.

In FIGURE 1 it will be noted that sheet 30, which is normally designated on its opposite side from that shown for Saturday-Sunday memorandum has been guidedly transported from its usual first position over the curvature of bars 20, 22 and to the oppositely disposed supporting surface. In other words it has been turned down to expose the Monday sheet 32. The edges only of the Tuesday, etc. sheets 34, 36, 38 and card 40 are exposed.

Each leaf set, comprising day sheets 30, 32, 34, 36 and p 38 and the terminal card 40, have substantially the same upright dimension but vary in width so that the day sheets 30-38 are retrospectively smaller datewise from the terminal card 40 which determines the overall width of each leaf set. Should the user desire to scan his notes for future weeks he merely thumbs one, two or three or more terminal cards, lifts the selected card, and at a glance may see his notes for the selected week.

The terminal card 40 of each set 28 is formed of a stiff card stock appreciably heavier than the sheet stock from which the day sheets 30-38 are formed. This accents, during manual manipulation, the leaf sets at the right or left edge so that a user may quickly in retroin making handwritten notations and other entries.

spect or forwardly thumb his calendar. for reference to notations which are otherwise concealed.

The retrogressive decrease in size of the day sheets 30- 38, date-wise, relative the width-of the terminal card 40,.results in each of the leaf sets being somewhat thicker at their inner or perforated edges than at the outer edge of card 40.

In other words the leaf sets are somewhat tapered. The sloping angular disposition of the supporting surfaces and 12 accommodate this tapered arrangement and aids in disposing the exposed sheets or cards of any set relatively fiat for ease This advantage is to be observed in the end view of FIG- URE -2. I

Block 52 is secured in valley 14 and rises a short distance thereabove between the inner edges of the groups of card sets. The presence at this point of block 52 aids in maintaining the alignment of the cards of the several plurality of the sets by preventing or reducing canting of the sheets and cards. This is supplemental to the alignment essentially maintained by the inverted arches 20, 22 and the guide member 42. It has been found that when the lowermost cards disposed on the two surfaces 10 and 12 are thus abutted against the block 52 the inherent friction which exists between the cards of the several superposed sets is suflicient to maintain alignment of cards that may not be abutting block 52.

It should also be noted that the upper corners of the various cards 30, 32, 34, 36, 3 8 and 40 are cut on a bias and that each may have obliquely printed thereon the name or names of a day or days of the week to which Having thus described my invention, I claim:

1. A memorandum calendar, comprising: means providing an upwardly open supporting cradle having a valley approximately normal to the user of such calendar; a pair of arched guide members supported relative said cradle in such manner as to be spaced apart from each other and to straddle the valley thereof; a plurality of leaves guidedly associated with said guide members for transport from side-to-side thereof; and an inverted resilient guide strap formed of thin, springy sheet material and disposed beneath and extending between said guide members in uniform spaced relation to the inner surfaces thereof and in juxtaposition to the inner edges of said leaves uniformly aligning the same relative said guide members.

2. A memorandum calendar comprising: means forming a base; guide arches supported in spaced apart parallel relation above said base; a plurality of memorandum pages slidably mounted on said guide arches; an arched guide strap uniformly underlying said guide arches, and extending therebetween, said guide strap being formed of thin, springy sheet material and being resilient and outwardly biased toward the inner surfaces of said guide arches to press on the inner edges of said pages; and said guide strap having outwardly directed foot flanges provided with notches to engage the legs of the guide arches adjacent said base.
